I have a 1964 boat and motor, (75 hp johnson) that has been sitting for 6 years. There is an electrical junction box on the side wall of the boat that is just trashed. It houses a solonoid and some other components that I am not sure what they are but they are all rusted. It also has wires that the insulation is dry rotted. Is there any way to get new updated parts to replace these old crusty relics?
